I have a 1994 Chevrolet Caprice with a 5.7 engine. I recently had the optispark changed to stop a backfiring problem. The day after that I got the fuel pump changed. When I went to pickup the car I couldn't drive off unless I had the hazard lights on. Here's the other part of the problem, when I turn on the headlights the car cuts back and cuts off. My taillights are so dim that u can't tell their on and the third brake light stays on...unless I have the hazards on. However, the hazards blink slow but never completely cut off and while the hazard lights are on my third brake light functions normally, but no other lights. I've checked fuses and wires, nI need help
